JERSEY, ASSIGXORS TO THE LEES )[ANVFACTIRIG To all whom it may concern- Be it known that we, GEORGE A. STEDMA'N, residing in the city, county, and State of New York, and DAVID VIR. Srniinms",A residing in Elizabeth, Union county', New Jersey,` both citizens of the United States, have invented certain Improvements in Pipe or Hose Couplings, of which the following isa specification.

Our invention relates to that class of coup-l lings wherein the sections of hose or pipes to be coupled each carries a member of the coupling and thecoupling together is eected without the aid of screws;l and theobject of the invention is to provide a coupling which may be manipulated quickly by any one, no mattei' 'how inexperienced he may be, vand one which will be perfectly tight under all ordinary conditions. Our invention will be fully described hereinafter, and its novel features carefully defined in the claims. j

In the accompanying drawings, Figure 1 is a longitudinal section of a hose-coupling embodying our improvements. .This view shows the two members detached. Fig. 2 is an elevation of the coupling, showing the members locked or coupled together. Fig..3 is an end view of the major member of the couplii'ig. Fig. L is a viewillustrating the application of our coupling to the coupling of an ale or beer faucet to a pipe. Fig. 5 is a sectional view of a modification.

Although we have herein shown only two applications of our coupling, it is equally well adapted for coupling' pipes or hose together and for coupling pipes or hose to nipples and nozzles of all kinds.

Referring primarily to the first three iigures, A is the major member of the coupling as a whole, and B is the minor member. The major member comprises a tube 0,- to which is secured one section of hose X. This tube a. extends through a tubular casing a', which is capable of rotating on the tube. On the tube a is a collar a?, which lits the bore of the casing u in the manner of a piston, and is provided with ya packing-ring a3 on its outer face, of rubber orsimilar soft packing material. The tube ahas a bearing at-A a* in the rear closed end ofthe tubular casing, and the .bore-ofthe casing.

collar a2 formsa second bearing for the tube andr keepsithe lattercentral1y situated in the 'ithin the bore of the casing and embracing the tube a is a coiled spring' n.5, whiehabuts at one end againstthe ss.A

shoulder at the rear end of the casing and at the other against the inner'face of the colla-r ai. This spring tends to drive the tube t-oward the open end or mouth of the casing; but a limiting-shoulder u, formed on the tube, seats itself against the rear end of the casing and keeps the spring under some tension. The shoulder u is formed by securing to the tube a a grooved or roughened nipple ai, to D which the hose X is secured. In` thecasing a', at its open end, formed an L-shaped slot as, the form of which is best seen in Fig. 2.

The inferior 'member B is in the form of a short section of pipe, to which is secured a.

' section of hose X. The internal diameter of the memberB is the same as the external diarneter of the tube u, and the external diameter of said member is the same as th'e'diameter of g the bole in casing u', whereby said member'may be slipped over the end of the tube a, which extends beyond the collar ai' and projects from the open end of the casing, and is made to enter the latter. On the member B is a stud or projection b.

Fig. 1 shows the members separated and in their normal condition. To effect the coupling, it is only necessary to bring the two members together, pushing the inferior membr over the extremity of tube u until its end bears on and againstthe packing-ring as, the stud l entering the slot a?. The members are now pushed together as far as the slot will permit, the collar a2 yielding and compressl ing the spring a behind 1t. lhe casing a 1s now turned with the hand unt-il the stud b engages the lateral branch of the slot, as seen in Fig. 2. This locks the members together. The spring keeps the packing pressed up tightly against the member B and forms a tight joint. The members may be instantly disengaged or uncoupled by reversing this operation.

To prevent dirt from getting into the interior of the casing through the slot n, the piston-like collar a'2 is made wide enough to cover the slot and is arranged lo stand in po- 25 vent the hand from slipping.

sition to cover and close the slot normally, as

v Seen in Fig. 1.

The inferior member B may be a pipe or a nipple, as it is merely a plain tube provided with a locking-studl In Fig. 4 we have shown the application of our coupling to the nipple of a faucet. InV this gure C is a faucet of an ordinary kind, of which the outlet-nipple forms theinferior member B of the coupling. 1o In this viewa metal pipe or tube X2 replaces the hose Xof Figs. l and 2. In other respects the coupling is the saine as that before described. M

Fig. 5 is a View illustrating a slight modification. In this case the hose X is attached directly to the tube a, -and the member B is reduced in size to receive the hose X. By this construction hose of smaller diameter or having an internal diameter nearly the same 2o as that of tube a may be coupled together. 'lhis view serves to illustrate the interior 'construction when the two elements are coupled or locked together. The casing a may be roughened exteriorly, inorder to pre- It may have any convenient form exteriorly.`

Having thus described our invention, we claim- 1. In a coupling, the combination of a tube 3o a, having fixed on it a collar a2, with a packing a on its face, a tubular lneinber B, adapted to fit over the tube a, with its end abutting against said packing, a sliding casing on the tube a., a spring arranged between the collar a? and some part ot' said casing, and reciprocal fastenings on the said casing and the member B, substantially as set forthf 2. In acoupling, the co1nbination,with a tube a, having fixed on it a limiting-shoulder co6 and a' collar a2, the latter having on its outer face a packing a3, of a tubular member B, adapted to fit over the tube a, with its end abutting against the packing a3, a sliding casing on the tube a., having,a bore in which the collar a2 fits, a spring a5 within said casing and ein bracing the tube a, said spring abutting at one end against the collar a2 and at its other end against some part of said casing, and reciprocal fastcnings on the said casing and the member B, the' limiting-shoulder a being exterior to thecasing, substantially as set forth.v

In witness whereof we have hereunto signed our naines in the presence of two subscribing witnesses.
